Heatwaves: A Growing Threat
Climate Change and Heatwaves
Climate change has led to about 18°F (1°C) of average global warming since the late 19th century, and this warming is causing heatwaves to become more frequent, intense, and longer-lasting.
Population Exposure to Heat
Population exposure to heat is increasing due to climate change and this trend will continue as the global population grows and more people move to urban areas.
Health Impacts of Heatwaves
Heatwaves can have a range of negative health impacts, including heat exhaustion, heatstroke, and death. Heatwaves can also exacerbate existing health conditions, such as cardiovascular disease and respiratory problems.
Economic Impacts of Heatwaves
Heatwaves can also have a significant economic impact, leading to reduced worker productivity, lost work hours, and damage to crops and infrastructure.
What Can Be Done?
There are a number of things that can be done to reduce the risks associated with heatwaves, including:
- Improving early warning systems
- Developing and implementing heatwave response plans
- Increasing access to cooling centers
- Educating the public about the risks of heatwaves
- Implementing measures to reduce greenhouse gas emissions
